Thinking of using these on my new reef tank spslps. Using t5 right now with no issues but would love to have all the benefits of led. These are off eBay anyone have any insight if the specs seem good enough for growing my coral thanks for the help

If the T5's were working, be careful and start the LEDs on a low setting and work them up as your coral adjusts. Lots if variables, lenses, power efficiency, tank depth, type of coral, led color, etc. So best thing is go slow and don't underestimate the power the LEDs have.

With out a doubt IMO a proper led fixture will grow any coral that can be grown artificially using light. Clams, sps, the lot of them can be grown. Just be advise the light is only part of the solution to growing hard corals. I think a large number of folks on this forum have moved to LEDs. But even T5's can grow hard corals under proper conditions and tank size.
